From Diablo Wiki
During the events of the demonic invasion 20 years ago, Jerhyn was described by some (including old Lysander) as "Young Jerhyn", and was likely in his twenties, which would make him middle-aged by now if he is still alive.
Whether or not he is alive, or has gone crazy from the demonic corruption like many others is unknown.
In Diablo II
He's not a merchant and doesn't buy or sell anything, but he does give out a quest that must be completed to advance to Act Three. Jerhyn's location changes in an unusual way; he is standing near Warriv when a character first arrives in Lut Gholein, eager to give his welcome message. He remains there until a character talks to him, or until the Arcane Sanctuary quest is activated, at which time Jerhyn relocates to the lavish Palace in the center of town. Characters must talk to Jerhyn after defeating Duriel, before they are permitted to sail on to Act Three.
In Diablo III
If an aged Jerhyn still rules the mighty city of Lut Gholein in Diablo III remains to be seen.
